First of all, let me say this: let's not turn this into a 4 vs: 6 thread. I like them both and really don't give a damn about your position on this non-issue.
All the legal stuff out of the way, let's talk engine. First of all, this project is well advanced. The engine is already together and the 20 minute cam run in has been done. But let's talk about how we got to that point first... This motor is a 2432 Raby kit. It uses the LE200 heads and stock 2liter cylinders. The stroked crank is 84mm I believe so think of it as a super-stroker. It will run Jenvey throttle bodies and SDS injection. The EFI sensors I have chosen to use will be TPS, CHT, MAP, IAT, O2 in closed loop, and I think that is everything. Injectors are Ford Red Top. This motor requires quite a bit of engine block clearance so as they say, don't try this at home... It took me about three trips down to Original Customs to put the engine together. I used McMark's shop so I could get his free advice which he of course charges me for, and I don't get distracted by wives wondering how much all of this costs. Plus Mark has an engine break-in stand that allows us to fire it out of the car and correct anything that might be wrong without having to pull an already installed motor. Here is a dyno sheet of one of these motors that Jake actually built. I would expect that my result might be within 10% of his. :Insert fingers crossed smiley here: Attached thumbnail(s) |

Sorry Mark. Think of yourself as a pioneer. (IMG:style_emoticons/default/smile.gif) For those of you who want to know why we are building a custom harness here is a bit of an explanation. The harness that is supplied with the SDS system is made to fit any application. It has wiring long enough to get to anything you can dream up for mounting locations. Add to this, the harness appears to be a little less than ready for the harsh environment of an engine compartment. It looks more like something you might hook up an office computer network.
For this reason, I took the 'delete harness' option when ordering. This takes $250 off. Granted, it will cost more than that to have Mark build me a harness but I will not have coiled up harness under the passenger seat and in the engine compartment. Ross at SDS answers his own phones so he is a ready reference... Mark is a bit more of the lap top programmable aftermarket EFI guy... He likes all the tables and graphs you can generate using Megasquirt and such... I just want to drive. Now to be fair to SDS, their harness must work well. They put it in retrofit airplanes and I have not been hearing of them falling out of the sky due to harness failure. (IMG:style_emoticons/default/sad.gif) |
